To all whom it may concern:

Be it known that I, EsTnY M. TURNER, a citizen of the United States, residing at Pasadena, in the county of Los Angeles andy State of California, have invented a new and useful Phonograph, o f which the following is a specification.

This invention has reference to improvements in phonographs and is designed to produce a machine of this character with which the sound may be recorded or reproduced to as great an extent as desired even though far exceeding the limits ofthe record tablet, the ystructure being such that when the record on one tablet is about exhausted or the limits of the tablet arc about reached, a second tablet will come into action automatically so that during the recording or reproducing of the sounds with the second tablet a third tablet may be placed on the machinel after the removal of the first tablet and on the completion of the second tablet the third tablet will be automatically introduced into action, and this operation may be repeated indefinitely so long as the operator desires. f

The invention will be best understood from a consideration of the following detail description taken in connection with the accompanying drawings forming a part of this specification, in which drawings,

Figure 1 is a side elevation of the machine. F ig.V 2 is a central vertical section longitudinal of the machine. Fig. 3 is a plan'view of the machine Fig. 4 isla section on the line A-B `of Fig. 3. Fig. v5 is a sectional view of a sleeve or adapter.- Fig. 6 is an end elevation of the machine. Fig. 7 is a section on-the line C-D of Fig. 3. Fig. 8 is an end view of one of the record mandrels illustrating the lock for the record tablet. Fig. 9 is a detail view of the mechanism for operating the feed nut.

Referring to the drawings there is shown a base 1, at the opposite ends of which are spaced standards `2near opposite sides of the base and these standards carry rods 3 elevated at an ap ropriate distance above the base and extending from one end to the other at opposite sides of andl at equal distances from the centerline ofthe base. In the middle line of the base are tw standards 4, 5, each having formed as part thereof 4or fixed thereto a 'sleeve 6 extending toward.

' dicative of any manner of causing the end of the base 1. These sleeves terminate at the ends or have secured to their ends ball cups 7. -Mounted within the sleeves 6 are other sleeves 8 extending at each end through the ball cups. At one end, that is the end toward the middle of the base each sleeve 8 carries a ball cone 9 which may be attached to or form part of a clutch member 10 also mounted on the sleeve in fixed relation thereto. The other end of the sleeve 8 carries another ball cone 11 attached to or forming part of a hub 12 carrying at the end remote from the ball cup one end of a cylindrical mandrel 13 projecting over the sleeve 6 in concentric relation thereto and toward the middle of the base 1.

Entering the end of the sleeve 8 carrying the mandrel 13 is a screw pin 14 terminating at the inner end in a point 15 while at the outer end this pin is entered by a tapered screw 16 forcing it into firm engagement with the corresponding end of sleeves 8 thus uniting the pin 14 to the sleeve 8 in such manner that the pin may be ad'usted longitudinally of the sleeve and then ocked by the screw 16. The pin 14 is shown as provlded with a portion 17 having screw threads formed thereon and this portion is desigled to enter a correspondingly threaded portion of the interior of the sleeve 8.

Extending between the facing ends of the sleeves 8 is a shaft 18 having its intermediate portions provided with screw threads as shown at 19, this intermediate portion being preferably of greater diameter than the rest of the shaft and the screw threads are of a pitch such as is usually employed insound recording and reproducing machines. The ends.' of the shaft 18 are .reduced in diameter and enter the correspondin ends of the sleeves 8 and the extreme ends of the shaft are engaged by the pointed ends 15 of the pins 14 entering center cups in the ends of the shaft, these pointed ends 15 of the pins 14 serving as 'centerin bearings for `the shaft. Fast to .the sha t 18 at one end of the threaded portion 19 lis a pulley 2() by meansof which rotative movement may be imparted to the shaft from any appropriate motor. This pulley 20 is to be taken as inthe rotation of the shaft 18 either by belt or other- Wise. 1 f

At'the portionsof the shaft 18 adjacent tothe clutch members 10 are other clutch members 21 constrained to rotate with the shaft each by aspline 22 but which clutch members may be moved longitudinally of the shaft into and out of engagement with the respective clutch members 10 so that either one of the mandrels 13 may have r0- tative motion imparted thereto as may' be desired. l

Mounted on the rods 3 at each end of the machine is a carriage composed -of two sleeves .23, 24. The sleeve 23 is mounted on one rod 3, while the sleeve 24 is mounted on the other rod 3 at the same end of the machine as is the sleeve 23, the two sleeves 23 and 24 at the same end of the machine being connected by yokes 25 so that .the sleeves '.will move together.

The carriages are capable` of moving along the rods 3 for a distance about equal to the .length o f the corresponding mandrel 13 and the length of the screw section 19 of the shaft 18 is such as to impart the appropriate motion to the two carriages as will hereinafter appear.

Each rod 3 carries a sleeve 23 near one end and the s'leeve 24 of the other carriage near the other end. Mounted-on the sleeve 23 at one end of the machine is a tubular arm 26 having an angle neck 27 lseated in an annular bearing 28 carried by the corresponding sleeve and the arm 26 is held to the sleeve by a screw pivot 29 extending axially of'the neck and entering an appropriate threaded socket 30 carried by the bearings 28. The free end of the neck 26 within the bearing 28 is in communication with another neck 31 similarly mounted in the bearing 28 by means of a screw 32 similar to the screw 29 and the other end of the neck 31 may -receive any appropriate sound conveying conduit whether-of the amplifying character or not.

The end of the tubular arm 26 remote from that formed into the neck 27 carries a sound box 33 either formed rthereon or at-l tached thereto and this sound box may be,

of any appropriate character, they construction of the sound box not entering into the present invention. yIn order that the sounl box may be manipulated as desiredg'the arm 2,6 is formed with a manipulating handle or extension 34. Attached to the sound box 33 or to the corresponding end of the arm 26 there' is 'one end of a lever 35 hinged to the opposite member 23 or 24 of the corresponding carriage and alsoprovided with a manipulating extension 36 similar to the manipulating extension 34 ofthe arms 26.

The member 24 of the carriage isV longerl than the mandrel 13 and for a portion of its` length is reduced in kexternal diameter as indicated at 37 in Fig. 4, this reduced portion constituting a seat for a sleeve 38 capable of turning on the sleeve 24 and this sleeve 38 at the end toward the sound box provided withan off-set arm 39 having its free end parallel with the axis of rotation of the sleeve and under-riding the handle or extension 34 so that when the latter is depressed the arm 39 will be engaged by said handle and the sleeve 38 will be given a short rotative movement about the axis of the member 24.

The end of the sleeve 24-remote from that carrying the hollow arm 26 in one case and the lever 34 in the other case has a lateral extension or arm 40 vadjacent to the screw portion 19 of the shaft 18. This arm 40 is formed at the outer end with a recess 41 housing a block 42 provided with a stem 43 projecting into the arm toward the rod 3 and having its end adjacent to the rod 3 bent at an angle to project beyond the corresponding face of the arm 40 as shown at 44. The sleeve 38 adjacent to the arm 40 is pro.- vided with a finger 45 shaped to engage the end 44 of the rod or stem 43 in such manner as to cause the longitudinal movement of the block 42 in the recess 41 when the sleeve 38 is rotated in the proper direction. Outside the recess 41 the block 42 is engaged hy `a spring 46 tending to move the block 42 outward. Therblock 42 carriesa nut section 47 adapted to the threaded portion 19 of the shaft 18.

The sleeves 23 and. arms 40 are provided with meeting lugs 48 and through the corresponding lugs on the same side of the machine extends a rod 49 headed at each end beyond the lugs and capable of moving through said lugs. The lug 48 upon each sleeve 23 also carries an adjustable pin 50 so positioned as to make contact with the other lug 48 on the same .side of the machine under conditions which will presently appear.

Mounted on the base 1 beneath the clutch member 21 is a lever 51, this lever beingl pivoted at one end to the base as indicated at 52.

Beneath the clutch member 20 is another lever'j53 pivoted atvone end of the base as indicated at 54. Rising from each lever is an arm 55 connected tothe corresponding clutchmember 21 or 22 as the case may be so that when the lever is moved on its pivot the clutch member w'illbe moved longitudinally on the shaft 18 into orout of engagementwith the meeting clutch member coupledmto the corresponding mandrel. The two levers 5,1 and 53 have their pivot connections at one side of the center line of the ma'- chine and extend toward the other side of they machine wheretfhe free ends of the levers @are connected by a link 56 so that these two levers @are constrained to` move t ether. The link 56 near'jthe lever 53 carries n upwardly projecting in 57 of suflicient eight t'o be engaged by a ug on block 58 carr d by esmas livotally connected to the link 56 near.

the pin 57 is one end of a'lever 59 pivoted 'to the base about the center line thereof, that 1s,

beneath the shaft 18, and this lever extends,

to the other side of this center line and into the path of the arm 40 of the carriage member 24 on the corresponding side of the ma chine. The free end of thisjlever carries a set screw 60 so that the relative time of contact of the arm 40 with the lever may be adjusted.

'lfhe accessible end of each mandrel 13 is provided with elastic fingers 61 preferably at diametric points within the mandrel and the free ends of the spring lingers project .lingers 61 yielding to such movement and when the tablet is on the mandrel to the full extentthen the ends 62 of the spring lingers snap in the path of the tablet thus holding it on the mandrel.

The end of the mandrel remote from that onto which the tablet is first placed is provided with a. radial circumferential flange 65 and adjacent to this flange the mandrel is providedI with a perforation 66 through` which extends the free end of a spring 67 fast to the interior of the mandrel. The sleeve 63 is provided with an end notch 68 entered by a radial lug 69 on the mandrel adjacent to the spring 67 and this spring is designed to have its free end enter the notch in the mandrel So as to take up any looseness of lit between the notch of the mandrel and the lug 69. are designed to cause the tablet to rotate with the mandrel, without interference however with the ready removal of the tablet from the mandrel.

The mandrel 1.3 is cylindrical, but such mandrel may be made tapering, after the ordinary practice of cylinder record machines. or the mandrel 13 may be adapted to tablets with internal tapers by the employment of a taper bushing 70 shown in Fig. 5.

Let it be assumed that it is desirable to make a sound record much longer' than is possible on a single tablet. Also let. it be assumed that ajsuitable record tablet has been placed upon the mandrel at the right hand end of the machine and that the sound rllhe parts just described is being recorded in the usual manner. ln the position shown in Fig. 3 the sound box has reached about the limit of its travel toward the right and the arm 40 of thesleeve 24 of the carriage for the said sound box is brought `into engagement With the screw 60 of the lever 59 and the actuation of this lever by the continued movement ot the carriage causes a movement of the lever 53 in a direction to move the clutch member 22 out of engagement with the clutch member l0 and thus uncoupling the mandrel at the right hand end of the machine, as viewed in Fig. 3, from the shaft 18 which is assumed to be continuously rotating under the action of a suitable power applied thereto through the pulley 20 or by means of other driving devices.

As the clutch member 22 is being moved out of engagement with the clutch member l0, the clutch member 21 is being moved into engagement with the clutch member 10 of the other mandrel, that is the one at the left hand endf'of the machine, through the link connection 56 between vthe levers 53 and 5l. The lparts may be so. adjusted that the coupling of the mandrel at the left hand end of the machine to the power shaft will take place just prior to the uncoupling of the mandrel at the right hand end of the ma` chine from the power shaft.

The parts are so adjusted that just prior to the uncoupling of the mandrel at the right hand end of themachine from the power shaft the rods 49 are so `moved by the progressive travel of the carriage at the' righthand end of the machine as to have their other ends move the carriage at the lefthand end of the machine a sutiicient distance toward the right to bring the nut 47 of said carriage into engagement With the threaded portion 19 of the shaft 18 so that as the recording at the right hand end ot' the ma* chine ceases it Will begin at the left hand end of the machine. It is preferable that the recording should begin on the left hand end of the machine just prior to ceasing at the right hand end of the machine so that there is a slight overlapping, but with the machine properly adjusted this Will not interfere With the reproduction of the sound. The recording proceeds continuously, and the operator by a suitable manipulation of the 'extensions 34 and 36 lifts the sound box 33 out of engagement With the record tablet, and this manipulation of the extensions 34 and 36 causes a rocking of the sleeve 38 by engagement of the extension 34 with the arm 39 to a sutiicient extent to cause the finger 45 te operate on the pin end 43 and Withdraw the nut- 47 from engagement With the thread'- ed portion 1t) o the shat't 18. rl`he carriage at the right hand end ot the machine" may new be pushed toward the other end of the machine to a suicient distance to bring'L-,th'e sound box into operative relation .to-'the imtial end of the record tablet, thev full tablet having been previously removed and a new table substituted, or this may be done after the carriage has been returned to its initial position. In the meantime the record Yis being produced upon .the tablet at the left hand end of the machine and the carriage there located is moving toward' the-right.'

Ultimately this carriage approaches the right hand limit of its travel when. the lug 58 will be brought into .engagement with the pin 57 vand move the link 56 in a direct-ion opposite to that in which it was moved by the carriagevat the right hand end of the maing clutch member of the mandrel at the right hand end of the machine thus starting the mandrel at thel right hand end of the -machineinto rotation.- The pins 50 are at the same time brought into engagementwith the respective lugs 48 and the carriage at the right hand end of the"nra`cline, previously moved to its initial position, will be caused to travel a short distance wit-h the carriage at the left hand end of the machine, this distance being suflicient to bring the nut 47 of the carriage at the riglit hand end of the machine into operative engagement with the threaded portion 19 of the shaft 18.

As soon as the second cylinder has receivedv its record and the mandrel carrying it has ceased to move, it may be removed from its mandrel and another fresh cylinder put in its place ready for an additional" record, the carriage and sound box individual to such end of the machine havingbeen moved to its initial position so that when the premay be.

ceding record is finished the newA record may continue as before. `By this means the recording may continue uninterruptedly as long as necessary or desirable.

The machine thus -provides means for the continuous recording of sound without in' terruption and the reproduction of such records may be caused on the .same or a like machine even though the composition recorded covers many tablets of a size convenient to handle. l i

While the sound conduit for either receiving or amplifying recorded sounds is not shown in the drawing it will be understoodl that the two necks 31 will have a common connection to the receiving or the delivery end of a suitable sound conduit' as the case There need be no interruption-whatsoever in the continuity of the record asa whole even though it cover many sound record screw, clutches between the screw and respective tablet holders, operating means for vthe clutches acting to alternately move the clutches into position, sound boxes one for each tablet holder, elongated supports for the sound boxes parallel with the longitudinal axis of the screw, a feed nut for each sound box movable therewith and pivotally mounted on the respective sound box sup-` port, and means under the control of each sound box support for moving the feed nut of the other sound box into engagement with the feed screw;
